Well I've completed pretty much every other problem so far except this one, it stumps me. I believe I must complete the square but I've forgotten how I must go about doing that. I tried it already and nothing worked out and it didn't factor correctly to the answer.

$\displaystyle y=1/4(x^2-2x+5)$

steps please

vertex is supposed to be at (1,1), focus (1,2), directrix y=0
